Kefir has some unusual characteristics that have been documented by researchers. A study from 2019 demonstrated that kefir contains a strain of probiotics that can survive temperatures as high as 105 degrees Celsius. This means that the probiotics can live through boiling water, which is something that no other probiotic strain has been able to do. This could explain why kefir has been used for centuries as a remedy for many illnesses, as it is much more hardy than other probiotics. In addition to its unusual probiotic characteristics, kefir is also known for its pleasant, slightly sour taste. Source
